ADJ U STABLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 541,249, dated June 18,1895.

Application filed November 28, 1894. *Serial No. 530,214 (No model.)

To all whom it may concern:

Be it known that I, FREDERICK 0. PRICE, of the city and county of NewYork, inthe State of New York, have invented a new and usefulImprovement in Adjustable Chairs, of which the following is aspecification.

My invention relates to an improvement in adjustable chairs, with theobject in view of simplifying their construction and rendering themovements easily controlled by the operator.

The particular form of chair which I have chosen to embody my inventionis one adapted for use as a barbers chair, although the several featureswhich I shall hereinafter call particular attention to may be utilizedin connection with dental or surgical chairs, if so desired.

In the accompanying drawings, Figure 1 is a view of the chair in sideelevation with the parts in the position which they assume when theoccupant is sitting upright or in position for hair-dressing. Fig. 2 isaview in side elevation, showing the pedestal in vertical section, theparts being in the position which they assume when the occupant istilted back into a position for shaving. Fig. 3 is a top plan view ofthe seat-frame andthe chairsupporting yoke the upper part of the chairbeing removed; and Figs. 4, 5, and 6 are enlarged views of parts indetail.

The pedestal is denoted by A and is here shown as terminating insupporting legs a. The pedestal is internally screw threaded and thechair supporting spindle B is externally screw threaded to register withthe screw threaded interior of the pedestal.

The spindle B is made hollow for the reception of the stem 0 of a set ofstops 0 secured to the upper end of the stem 0 for locking and releasingthe chair relative to the sup-.

porting spidle B. The upper end of the spindle B is provided with anannular recess 1), for the reception of the hub D of the yoke to whichthe body of the chair is pivoted. The opposite arms d and d of the yokeare fitted at their outer ends to receive pivotal bolts e which engagelugs on the arms cl d and on the base of the chair to pivotally securethe chair to the yoke.

The base frame of the chair is denoted by of the yoke.

F and consists of side bars'and cross bars, as is common, and froin thebase frame F there are uprising posts f, f at the rear and front forsupporting the back and arms of the chair, as is common. I have chosento form the postsf, f and the side bars of the base frame of L orU-shaped iron, more particularly for the reception of certain operatingrods, which I shall hereinafter more particularly refer to.

From the base frame F there depends a supporting frame F for thereception of the foot rest frame F In the foot rest frame F 1 provide afoot rest G, so balanced upon its pivotal supports that when the chairis in the position shown in Fig. 1 or its-upright position, the footrest Gwill present a flat surface g to the foot of the occupant, andwhen the chair is tilted back into the position shown-in Fig. 2, thefoot rest G will, under the influence of gravity, roll over into theposition shown in Fig. 2, presenting-an upholstered or cushioned surfaceg for the reception of the leg of the occupant.

The tilting back section II is pivotally secured to the postsf at h andhas secured to it a sector bar 72. in positionto engage a spring dog 71.(see Fig. 4) which latter is fastened to the inner face of the postf.The view taken in Fig. 4 is an enlarged view in detail, looking from thefront to the rear, of the parts in the immediate neighborhoodof thesector bar h.

An operating lever I is pivoted to the post fat 7 and its short arm isconnected by a rod 2" extending along down within the U-shaped post f,connecting with one arm of the anglelevert' pivoted at the corner of thebase frame F, the other arm of the angle lever'i being connected by arod i (see Fig. 3) with one, arm of a lever 01, pivoted at t to asuitable support on the base frame F, the opposite arm of the lever ibeing connected by arod t with a spring actuated dog 11 in position toengage a rack bar f depending from the base frame F. The rod 71 and dog77 are supported by an arm d extending forwardly from thehub -D' Thelever t has its pivot 71 located as near as may be in axial alignmentwith the pivots e which connect the chair with the yoke, so that'thelever 2' will not be materiallydisturbed during the rocking movement ofthe chair and its pivotal connection i preferably consists of a ball andsocketconnection shown in detail and enlarged in Fig. 5.

The operating leverI is so arranged that its short arm, denoted by I(see Fig. 4), when the lever I is pulled backwardly, will engage thestock of the spring dog h and press the dog toward the postfout ofengagement with the teeth of the sector bar h, therebyleaving the chairback H free to be tilted. This same backward pull on the lever I will,through the connections 2", t t 2' aud t withdraw the dog 2' on the rackbarf thereby permitting the chair as a Whole to be tilted upon its yoke.It therefore follows that when the. lever I is pulled back, itsimultaneously releases. the

back so that it may be adjusted to any desired.

angle with respect to the body of the chair; releases the body of thechair as a whole, so that it may be tilted in. any desired angle withrespect to thepedestal and the foot rests automatically assumes its ownposition. As soon as the lever I is released, the back and the chairbody are simultaneously locked in their tilted adjustments.

The stem 0 which extends down within the hollow chair supporting spindleB has a screw threaded engagement at its lower end'with the nut M towhich are connected the inner arms of four pedals, denoted by O, O, Oand 0 extending radially away from the nut M at angles with each otherof about ninety degrees and'pivotally secured to. the pedestal A,preferably by an annular ringNsuspended.

from the center of the pedestal. When any one of these pedals O, Q, &c.,are pressed, upon by the foot of the operator, it will lift:

the stem 0 and'with it the stops 0 out of engagement with the hub D ofthe chair supporting yoke, so that the chair may be swung horizontallywithout moving the threaded spindle B and hence Without raising and 10W:ering the chair as a Whole. When, however,

it is desired to lower. the chair as a whole, it: maybe screwed up ordown by turning it while locked to the spindle B, the stem 0 in. themean time traveling up and down within the nut M.

The swinging back H is provided with a head rest, consisting of a. pad Khereshown in the shape of a cylinder and supported in a pair of swingingarms 70, the latter being.

pivoted to a vertical adjustable rack bar is secured to the back sectionH. A toothed dog is pivotally secured to one of the arms K or to thestem from which the arms is. diverge and extends down into position toengage an abutment k on an arm is, projecting rearwardly from the rackbar is. A- spring k tends to hold the toothed-dog k in contact with theabutment k to hold the pad K at any desired angle with respect to theback and a spring actuated dog k is located in position to hold the rackbark. at any'desi'red height with respect to'the back-section itself.

The mechanism by which the back section is swung relatively to the seatsection is such that the back may be tilted to a position forward of thevertical and there locked to accommodate occupants who are unusuallyround shouldered or whose heads are, from any cause, pitched forwardfrom the back of their shoulders. This feature is one of greatimportance, particularly in the use of the chair as'a barbers chair, asit permits the barber to come into close quarters with the head of theoccupant at the back of the chair and enables him to do his work betterand more expeditiously.

What I claim is- 1. The combination with the rearwardly tilting chairbodyandits support, of a. tilting back sectionpivoted to the chair bodylooking and releasing devices for independently adjusting the backsection relative to the body portion and independently adjusting thebody portion relative to its support and a single operating device forcontrolling said locking and releasing devices, substantially as setforth.

2. In combination, a chair body support, 'a rearwardly tilting chairbody, a spring actuated locking dog mounted on the body support inposition to lock the chair body in its severaltilted adjustments, atilting back sec-.

tion pivoted to the chair. body, a spring dog on the chair bodyinposition to lock the back section inits severaltilted adjustments, andan operating lever mounted on the chair body for simultaneouslyreleasing both the above named locking dogs, whereby the chair body maybeadjusted relatively to its support and the back section adjustedrelatively to the chair body,substantially as set forth.

3. The, combination-with the tilting chair body and itssupport, of aspring. actuated dog mountedon saidsupport in position to engagerecesses on the body of the chair, a

' vibrating lever mounted by a ball and socket pivoted in substantialalignment with the axis on which the chair tilts, an operating leverattached to the chair frame Within convenient reach of the operator anda connection between said operating lever and said vibratinglever foroperating the spring actuated dog, substantially asset forth.

4. In combination, a foot rest frame, a suitable support therefor, afoot rest consisting of a single piece pivoted to swing in the foot restframe, the said foot restbeing provided with a flattened side and with aroundcdside and being so hinged in the foot rest frame that when thechair is in its upright position the foot rest'will be drawn under theinfiuence of gravity to present its flat side toward the occupant, andwhen the chair is tilted backwardly the said foot rest will turn undertheinfluence'of gravity to present itsrounded side uppermost for thereception of the leg of the occupant, substantially as set forth.

[O uprising part of the body portion which normally engages the sectorbar for locking the back section in its tilted adjustments, and anoperating lever upon the body portion in position to engage the springdog for releasing it from the sector bar, substantially as set forth. :5
